With UnitTestBot, you can generate tests

• for a package,
• for a single class or a set of classes,
• for a method or a set of methods.

1. Open your Java project in IntelliJ IDEA.
2. Choose the required package, class or set of classes in the Project tool window.
   Right-click and chooseGenerate Tests with UnitTestBot or pressAlt+Shift+U.

3. Alternatively, in the Editor, place the caret at the required class or method.
   PressAlt+Shift+U or right-click and chooseGenerate >Tests with UnitTestBot.

4. In theGenerate Tests with UnitTestBot window, tick the classes or methods you'd like to cover with tests andpressGenerate Tests orGenerate and Run.
   

Now you can see the resulting test class or classes in the Editor.

Note: if you re-generate the test for a given class or method, it will erase the previously generated test forthis unit. To prevent this, rename or move the tests you want to keep. For more information, seeTest sources root.
